In 2019, there were about 1.47 billion international tourist arrivals worldwide, an international tourist arrival being

someone arriving in another country for leisure purposes. That's a historical peak for such

arrivals, that number climbing steadily upward from 1950, when there were only about 25 million such arrivals, before hitting

166 million in 1970, and 435 million in 1990. Part of this increase can be attributed to the

relative peace we've enjoyed post-World War II.

There have absolutely been conflicts, but even accounting for some of the somewhat major ones,

about how rare they are, especially considering just how many of them are taking off and landing at any given moment.

The internet has also become a thriving marketplace for transportation options, alongside platforms presenting places to stay and things to do,

once you get where you're going. As a result of this multi-factor tourism boom, the combined

travel and tourism industries, and their direct, indirect, and induced impacts accounted for about one in four of all new jobs created
